Since June 2001 PanoCube converts multiformats panos to QuicktimeCubic Projection movies. Freeware (Windows) and more featured shareware (Windows, Linux) versions are available.
The only program not depending on QuickTime libriaries - runs virtualy on any computer, even from floppy (size is about 20-30 Kbs).
The only native Linux pano to QuickTime converter.

100% PTViewer (Java) compatible movies - non tiled, placed in the right order. If tiles order have changed (due optimization, see above) the program outputs valid PTViewer's param "order" - just cut and paste it into your site to get things working;
